Not sure why but during the HTC Evo and Nintendo coming out with the 3DS having the screen be 3d (Stereoscopic since you can use it without lenses) didn't take off.

The iPhone 15 and 16 pro models can take 3D photos and videos right now https://support.apple.com/guide/iphone/spatial-photos-record...

The 3DS was fun but it was gimmicky, and it wasn't great.

I would love to have a 3d tv that works without glasses even if it was a limited depth thing (like multiple screens on top of each other to create real depth within a confined space) but I think the technology of the 3DS screen wouldn't scale to larger screens.

iirc this is effectively what looking glass displays do [0], or at least the early prototypes I saw, split a projected beam across 16 or so panes of glass. I've only seen the little one in real life but it was pretty enchanting. They go up to 32" and 64", something like 20,000 dollars tho [1] I don't know if they've actually made any sales of the larger formats

I was recently googling for whether these displays supported Apple Spatial Video and the answer was yes after some 3rd party conversion and playing media back straight from the iPhone it was recorded on, sounded annoying but feasible [2]

What is wild is that I saw a flat screen lenticular Canon display playing some custom DOOM clone in about 1998 at a video game developers event. It must have been at least 17" 4:3. It always seems it was something that accidentally fell back through time because it was so far ahead of its time. I remember feeling like a caveman because I put my head around the back like I was looking for the magic of how it worked.

The New 3DS was quite good, but being a relatively cheap Nintendo portable with backwards compatibility concerns it was pretty low resolution.

I was big fan of my HTC Evo, I found the 3D images to be immensely helpful when taking documentation photographs. I could take just two images and get all of the info I needed to capture vs taking ~8 from multiple angles and having to mentally envision the relative dimensions of the space afterwards.
